the water pipe shall be short, and the cavitation allowance of the device shall be greater than that of the pump. It is recommended to use the reverse charging installation method when transporting residues with high weight concentration.　　If there are sundries blocked, the pump will not be filled with water. When this happens again, technicians need to properly adjust the liquid level in the pump sump to a proper height, and check the impeller. In case of damage or aging,RumeisaLong shaft submerged slurry pump, it needs to be replaced in time,Rumeisa,　　 Change the oil: if the oil contains water, drain it, change the oil, seal the gasket, and then tighten the screw plug.　　Troubleshooting: first increase the water pressure, then inject water into the pump body,RumeisaUsed pipeline pump, and then start the pump. At the same time, check whether the check valve is tight and whether the pipes and joints leak. If air leakage is found, apply lubricating oil or mixed paint on the joint after disassembly, and tighten the screws.Anju, the leaked flammable, explosive and toxic liquid will cause fire, explosion and poisoning, and the consequences will be unimaginable.

　　 drainage and water injection with vacuum equipment: the self exhaust of centrifugal pump is the same as the negative pressure exhaust of vacuum pump, so the water ring vacuum pump is used for exhaust to achieve the of water inlet.　　Static water level refers to the water level before the pump is started.　　Only in this way can its service life be extended to a large extent.Online consultation,　　The operating environment is different: the key difference between the submersible slurry pump and the vertical slurry pump lies in diving. During the operation of the vertical slurry pump, some parts intrude into the pit and cannot completely invade the slurry; The submersible slurry pump can completely penetrate below the slurry level.　　It should be /-/ between. When the packing is worn, the packing gland can be properly pressed. If it is worn too much, it should be replaced. The whole commissioning process of the submersible slurry pump mainly includes the above five tasks,RumeisaRubber lining submerged slurry pump, which are mainly to pay attention to the details and the phenomena occurred during the operation, and timely deal with the problems in time to avoid being on duty Accidents during operation cause losses.　　For example, concentrate and tailings are treated in the concentrator, ash and slag are removed from the power plant, slime and dense medium coal are transported in the coal preparation plant, and slurry is transported in coastal river mining operations. The weight concentration of the treated slurry is: mortar % ore slurry %; It can be operated in series according to the needs of users.

　　Submersible slurry pump it fills the gap in the application of slurry pump. When the submergence is deep and there is no good mud outlet, the traditional slurry pump cannot be installed and operated, and the submersible slurry pump can supplement this part of the blank work point.Interpretation and observation, there is generally only outgoing cable, and the user needs to connect it separately during installation. If the connection is wrong, it will seriously affect the normal operation of the pump, so we should follow the correct steps to connect.　　During normal operation, the impeller of the slurry pump becomes tighter and tighter as it turns. The more it is used, the easier it will operate. However if the slurry pump reverses, it will directly cause the impeller of the slurry pump to fall off. The slurry pump must be disassembled and then re inspected, installed and tested.　　Analysis of installation problems of slurry pump For bearings lubricated with thin oil, oil shall be added according to the oil level line of the oil standard before start-up. Add (HL hydraulic oil in winter and (hl hydraulic oil in summer. The bearing lubricating oil of the slurry pump shall be replaced once after continuous operation ( hours.Rumeisa,　　All kinds of newly designed mechanical seals of submersible slurry pumps contribute greatly to the growth of market share.　　 Why does the demand for submersible slurry pumps increase greatly? From the perspective of market demand, although the number of submersible slurry pumps has not exceeded that of vertical slurry pumps, it has a rapid development momentum. The main reason is that the above-mentioned use is convenient and flexible; In addition, the application market of submersible slurry pump is also better than that of vertical pump　　 there is also a simple method to measure the vibration frequency of the pump by vibration method. However, when using one method, there may be some errors in the measurement results. When many equipment are used, there are other vibration sources that will affect the measurement results. Therefore in fact, it is mainly

　　Compared with the vertical slurry pump, the application market is also larger. In addition to the existing industrial and mining applications of the vertical slurry pump the submersible slurry pump can also be used as a mobile slurry pump,MikdadiaCorrosive pipeline pump, such as sand pumping on board, etc; Submersible slurry pump assembly workshop III. what are the advantages of submersible slurry pump　　Screw it down, and then remove the bearing inner race, O-ring, shaft sleeve and retaining sleeve in turn.Mikdadia,　　 Operation management of sewage pump operation management of submersible pump adjust the liquid level to make the water pump operate at the best operating point. After the equipment is selected, the intersection of the characteristic curve of the water pump and the characteristic curve of the device is the best operating point.　　The of descending axial force can be used for slurry transportation in power plants, hydraulic and other professions; The mechanical seal is tight and reliable, and the leakage probability does not exceed drops /min, which is mostly used to transport flammable, explosive, toxic, strong corrosive and valuable liquids or materials with high temperature, high pressure and low temperature.Jinka,　　The above is the reason for the insufficient liquid supply of the water pump when it is in use, as well as the specific methods to deal with this situation. We should pay attention to the regular inspection of the equipment during normal use to ensure that it is in use　　What is the cause of pump overload.　　In fact, when the submersible slurry pump is blocked during use, it will not only have a certain impact on the working efficiency of the equipment during operation, but also cause serious damage to the equipment itself so it is also a reminder that we are using it too

　　First, let&#;s talk about the familiar vertical slurry pumps. Here we refer to ZJL and SP submerged slurry pumps. Strictly speaking, the submersible slurry pump is also a vertical slurry pump, but it can be completely immersed in water when it runs, so it is a good choice　　Vertical height from water outlet center of pump base to flow destination (m)　　Let the medium containing some solid particles generate a certain flow rate, so that the equipment can drive the solid to flow when it is in use, so that the slurry can be transported. In terms of the principle of the submersible slurry pump, it is actually quite simpleDiscount,　　 the front and rear bearing glands are equipped with oil seals, which are padded with green paper or asbestos. There is a gap of .- mm between the rear gland and the bearing.　　In order to make the equipment perform better when it is used, but this also needs to be based on its working principle. It can not be adapted at will when it is optimized.　　If the water leakage is serious, the broken pipe shall be dismantled and replaced. Lower the lift and press the nozzle of the water pump into the water for .m.

　　The hardened mud layer collapses after softening, avoiding the phenomenon of burying the pump during use.knowledge,　　The solution to the excessive temperature of the water pump: when selecting the motor it is necessary to select one that matches its power and speed. In addition, the cooling fan should be installed on the main shaft. It is also possible to appropriately increase the number of fan blades, but pay attention to adjusting the vacuum pump　　 tailings transportation, various tailings ore, pulp, pulp, coal slurry,MikdadiaAh slurry pump, slag, slag treatment, etc.　　 selection of raw materials for flow passage parts: the raw materials for flow passage parts of the pump can be selected according to the particle composition, particle size, hardness, concentration,MikdadiaQJ submersible pump, acid, alkali and other characteristics of the transported materials.Mikdadia,　　The input quantity is related to many factors such as the rotating speed of the submersible slurry pump, the bearing standard, the number of stops and starts of the pump, the surrounding environment and the working temperature. Therefore, it is necessary to gradually accumulate the experience and add smooth oil in a reasonable and timely manner.　　 Then reinstall the equipment on the engine and install the rubber hose.　　Submersible pump is a common water lifting equipment for deep wells. During operation, the whole machine intrudes into the water to extract water from the underground to the surface. It is commonly used for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting ship load adjustment, landscape fountains, etc. Submersible pump is generally divided into clean water submersible

　　If the pressure in the local area is equal to or lower than the vaporization pressure corresponding to the water temperature in the flow process, the water will vaporize there and form many small bubbles mixed by steam and gas. The cavitation phenomenon is due to the bubble action when these small bubbles flow from the low-pressure area to the high-pressure area in the water pump,　　How to avoid this situation when the equipment is in use.Ash shamier,　　Characteristic ysis Starting mode the starting mode of the water pump control cabinet is divided into: full pressure start, auto coupling step-down start, soft start and variable frequency start. Proper starting mode shall be selected according to power supply conditions and other factors.　　Start the priming pump. Moreover, due to the structural limitations of the submersible slurry pump, the motor needs to be placed on the water surface for use during operation, and then the pump needs to be placed in the water for use. Therefore, the submersible slurry pump must beSvishtov,　　 If the hot water within ℃ is recommended, the hot water pump must be used, and the external tap water shall be connected for cooling during operation, otherwise the motor will not be burned due to too high medium temperature.　　 determination of model: for water pump or pump with physical and chemical medium similar to water, it is necessary to go to the relevant product catalog or sample, and make correction according to the performance table or performance curve of the model to see whether the normal working point falls in the priority working area of the pump.　　For example,Ash shamierSplit vertical pipeline pump, in the market, for example, the sweeping pump, some of which have a depth of more than meters, it is not suitable to use a vertical slurry pump under such a working condition, but it is extremely easy to use a submersible slurry pump.

　　 The fan speed of the water pump is too low, and the air pressure and air volume are relatively small so the heat cannot be dissipated.　　The industry is facing new technological innovations. Enterprises have also launched their own killer maces in the competition, constantly improving their R & D teams and studying the related core production technologies, so as to improve the competitiveness of enterprises in the market.　　Submersible slurry pumps are mainly used in mining, metallurgy, environmental protection, electric power and other industries to transport corrosive solid particle slurry. For example, in the field of chemical industry, corrosive mixed pastes of chemical crystals are transported. Electric ash removal, coal washing plant slurry transportation, etc. Submersible slurry pump bladenew product,Ash shamierRubber lining submerged slurry pump,　　Therefore, when the pump temperature is too high, you don&#;t need to panic. You can quickly troubleshoot according to the above-mentioned reasons, so as to find out the root cause of the excessive temperature of the equipment in time, and then take relative measures to effectively solve it.　　The Tao part also consumes part of it.　　Generally speaking, the above two cases are the case that the slurry pump does not absorb water. The solutions are also introduced. I believe that people can deal with this problem in time. However, if the problem is serious, you must not adjust it at will. At this time, you should find a professional

　　Submersible slurry pump it fills the gap in the application of slurry pump. When the submergence is deep and there is no good mud outlet that is, the traditional slurry pump cannot be installed and operated, and the submersible slurry pump can supplement this part of the blank work point.Test results, the biggest advantage is that it is flexible, convenient and easy to apply to various working conditions. The most important technical point of submersible slurry pump is the tightness between its motor and pump body Stability and reliability of seals.　　 WQ series submersible sewage pump has fixed and mobile devices, as shown in the figure. When the fixed driving device is selected, and its connecting line shall be parallel to the axis of the pump outlet) two lifting eye screws or lifting plates to lift the electric pump up and down,　　There are differences.Ash shamier,　　The operating environment is different: the key difference between the submersible slurry pump and the vertical slurry pump lies in diving. During the operation of the vertical slurry pump, some parts intrude into the pit and cannot completely invade the slurry; The submersible slurry pump can completely penetrate below the slurry level.　　Under the action of auxiliary devices, it can transport the slurry, and because the sealing device itself is special, it can also ensure the internal and external balance of the submersible slurry pump during transportation,Ash shamierVertical centrifugal slurry pump, so that the pressure at both ends of the equipment can be balanced during normal use　　This phenomenon shows that the failure of the pump is not only a material problem but also reminds the pump designers and producers that in addition to good working conditions, the pump should also have good corrosion resistance, high reliability and long service life. The pump shall be designed in addition to the conventional design method of fluid mechanics

　　Moreover, the leaked flammable, explosive and toxic liquid will cause fire, and the consequences will be unimaginable.　　Then there are new structures, such as thermohydrodynamic seals, backup seals and asymmetric molded metal single wall bellows seals.Tuz kumatu,　　For example, /c-ah slurry pump is a small-diameter slurry pump without impeller removal ring. When it is necessary to remove the impeller,Tuz kumatuHH slurry pump, we only need to fix the pump shaft, rotate the impeller in the opposite direction according to the rotation direction on the pump body, and then the impeller can be easily removed　　Potential is convenient and flexible. It is easy to operate. It can be operated by a fool who turns on the power supply under immersion; It has a wide range of applications. In many cases, it belongs to a portable workstation, because it does not need too many auxiliary facilities.Oliveira do Douro,　　In fact, the pumps I am going to talk about here have a wide range of uses. Pumps are required for both civil and military purposes, as well as for advanced technologies, especially in the mining, chemical, metallurgical and other industrial sectors. It is a widely used general mechanical equipment. Most pumps are corroded or severely corroded　　Its main features are as follows: the whole machine is a dry-type motor pump structure. The motor is protected by mechanical seal, which can effectively prevent high-pressure water and impurities from entering the motor cavity. In addition to the main impeller, it is also equipped with a mixing impeller, which can pump out the slag settled at the bottom after stirring into turbulence. impeller　　 The pump body (can not) bear the pressure from the outlet pipeline system. The standby pump in the warehouse should rotate (/ times a week to make the shaft bear the load and external vibration evenly. The belt CR drive is that the motor is on the (right) side of the pump from the inlet of the pump.

　　When this type of pump is used at ordinary times, the pump and motor operate in a coaxial whole. When it runs the motor shaft will drive the impeller of the pump to rotate, and then at this time, the rotating force can be brought to the medium, so that　　In the process of daily use, the s of these two sewage pumps are actually the same. The biggest difference between the two is that one is fixed and the other is mobile. WQ series submersible sewage pumps are generally equipped with an auto coupling device, which we call a fixed type. It is fixed in one place to cooperate with the pipeline discharge　　 The working properties of the two pumps are also different. Because the sewage pump is driven by a motor, it generally has good voltage impact resistance. The submersible pump is of the type of quick opening and quick closing, so it usually uses some small Flow and small pressure.Quality Assurance　　When the water pump is driven by electricity or diesel engine, its impeller (like an electric fan) rotates wildly, thus forming a vacuum in the impeller. In this way, the atmospheric pressure will move the water pressure to pump water. In fact, from a al point of view, it is to convert electrical or chemical energy into gravity　　After the submersible slurry pump leaves the factory, there is generally only outgoing cable, and the user needs to connect it separately during installation. If the connection is wrong, it will seriously affect the normal operation of the pump,Tuz kumatuBaigang deep well pump, so we should follow the correct steps to connect.　　Now you know the reason why the pump has air turbidity. In fact,Tuz kumatuSewage pump diving, this is a very common phenomenon. You don&#;t have to worry about it. Water pump can transport many things, oil, liquid metal, acid-base night and so on. It is a good means of transport.

　　Promote the continuous expansion of the sales network group.Good reputation,　　Will be scrapped. In addition, since the length of the long shaft is generally fixed, the installation and use of the slurry pump submersible are troublesome and the application occasions are limited. The submersible slurry pump is developed to adapt to increasingly complex working conditions and facilitate the use of users. Its use mode is more　　The discharge side of the pump must be equipped with a valve (ball valve or stop valve, etc.) and a check valve. The valve is used to regulate the operating point of the pump. The check valve can prevent the pump from reversing when the liquid flows back (the long shaft deep well pumps produced by our company are equipped with anti reversing check devices) and prevent the pump from being hit by water hammer　　Third, the whole industrial and mining system operates stably and the operation of the pump will not affect the work of the whole industrial and mining system.Tuz kumatu,　　 It may also be because the pump&#;s liquid supply pipe is blocked by other substances during normal use.　　The seal cannot bear the water pressure at this depth. Once the water leaks, the motor will not work normally, resulting in damage to the submersible slurry pump. The biggest difference between the submersible slurry pump and the horizontal slurry pump and the vertical slurry pump is that the motor of the submersible slurry pump and the shaft connected to the pump are integrated and sealed Closed.　　 If the head of the submersible slurry pump is too low or the head is higher than the practical condition, the flow will be large and the current will rise. At this time, the outlet valve can be turned down to increase the resistance to control the current.

　　Most of the time, we don&#;t know how to choose the pump when we buy it. In fact, we only need to choose the appropriate equipment according to our own use needs when we choose it. It&#;s more like that in a conventional family, when we use it,Al hayeBooster pipeline pump,Al hayeSubmersible pump can pump sewage,Al hayeAh slurry pump, the flow is small　　This phenomenon shows that the failure of the pump is not only a material problem but also reminds the pump designers and producers that in addition to good working conditions, the pump should also have good corrosion resistance, high reliability and long service life. The pump shall be designed in addition to the conventional design method of fluid mechanicsAl haye, and a thermal element is embedded in the stator winding to automatically protect the pump motor.　　The whole packing body, including the packing gland, packing ring and packing, needs to be disassembled; Submersible slurry pump Disassemble the o-seal ring, shaft sleeve, balance disc and key on the shaft in turn, and then the discharge section includes the last stage guide vaneLiverpool,　　Sex is different. Although the submersible slurry pump is widely used, some people outside the industry misunderstand this. In fact, the impurity pump, dredging pump, desilting pump, etc. are all in the application scope of the slurry pump　　The other mechanical seal is a split seal, which can be replaced without disassembling the slurry pump.　　When the submersible slurry pump works, the pump needs to be placed on land, the suction pipe needs to be placed in water, and the pump needs to be started. Due to special structural requirements, when the slurry pump motor is submerged in the water, the slurry pump and submerged slurry circulating pump need to be placed above the water surface, so they need to be fixed, otherwise the motor will fall into the water

　　During normal operation, the temperature of the motor is very high, some even as high as ℃. In this case, it is easy to burn the motor and replace it with a new one. In fact, one motor burns out at this time. Don&#;t worry about replacing it. You must find out the cause of the motor&#;s heating, or　　 Pipeline high-temperature oil pump, pipeline high-temperature chemical pump, pipeline high-temperature hot water pump. These models are designed to be formed on the basis of adding water cooling units, and the operating temperature can be as high as degrees or higher.　　The vertical sand pump is generally a submersible slurry pump.

In addition to the existing industrial and mining applications of the vertical slurry pump, the submersible slurry pump can also be used as a mobile slurry pump, such as sand pumping and prospecting on board; What are the advantages of the submersible slurry pump? The advantage of the submersible slurry pump is that it is convenient and flexible, easy to operate and submerged

　　If the shaft seal is not properly selected it will not only require frequent maintenance during operation, but also leak a large amount of transmitted liquid.Where to sell API,　　In fact, when the submersible slurry pump is blocked during use, it will not only have a certain impact on the working efficiency of the equipment during operation, but also cause serious damage to the equipment itself, so it is also a reminder that we are using it too　　The equipment of this series of sewage pumps can be fixed or mobile. When the fixed active equipment is selected, the chain cable shall be separately threaded into (against the pump outlet, and its connection shall be parallel to the pump outlet) two eyebolts or lifting plates to lift the electric pump up and down. Evenly and slowly along the guide rail　　 Next, the water seal, lock ring and other parts need to be installed.Al haye,　　The high-pressure water flows to the space occupied by the original bubble at a very high speed, and the heat generation is too large, resulting in the high temperature of the vacuum pump.　　If the oil seal ring of the shaft is seriously worn, replace it with a new one.

　　 selection of pump head: generally,　　 The fire control cabinet has fault alarm . When a single fire pump is working, it is not easy to be found in time in case of insufficient water source, power circuit failure, etc., resulting in damage to the fire pump.

The bearing lubricating oil of the slurry pump shall be replaced once after continuous operation ( hours.　　It generator and market formed at the beginning of construction have gradually formed a certain scale after more than ten years of rapid development. In the early stage,NajafDeep well pump, in order to meet the needs of market development, water pumps and generators

　　 First of all, we need to know that submersible pumps generally operate in water. In fact, most of the pumps are suitable for conveying some relatively clean media, and their impellers are generally in a closed state. However, one of the media conveyed by sewage pumps may　　 still water level of water well M　　In order to ensure the demand for water and electricity for production and living, many units, hotels and residential areas in various provinces and cities in China have purchased it and generators. Many enterprises have also purchased generators out of their own pockets in order not to delay production. Driven by this, it and the generator naturally become popularCreate brilliance,　　Other ysts believe that, at least in recent years, and China&#;s economic growth trend will maintain a high speed. Therefore, which is undoubtedly an opportunity for it and the generator industry. In water pumps and generators, especially　　With water, you can start working.　　During normal operation, the temperature of the motor is very high, some even as high as ℃. In this case, it is easy to burn the motor and replace it with a new one. In fact, one motor burns out at this time. Don&#;t worry about replacing it. You must find out the cause of the motor&#;s heating, or

　　Some of them are OK. For irrigation and other purposes, in fact, we choose to use larger flow. Let&#;s take a look at the method of selecting pumps.How much is it,　　 The fan speed of the water pump is too low, and the air pressure and air volume are relatively small, so the heat cannot be dissipated.　　 Service conditions　　Therefore, the stator winding will be burnt out due to excessive temperature rise.Najaf　　Where ρ—— Density of transmission medium liquid (kg/m; γ—— Gravity of medium liquid (n/m; H -- pump lift (m); Q - water pump flow (m/s); G - gravitational acceleration (m/s.　　The difference between the shaft power P and the effective power PE is the power loss in the pump, which is measured by the pump efficiency. The pump efficiency is the ratio of the effective power and the shaft power, which is measured by η Indicates.　　It is an auxiliary means of on-site monitoring. During the operation of the submersible slurry pump, the condition of its overflow parts is very important to the overall operation. In order to let everyone know more about the equipment, we will learn how to adjust the impeller clearance of the pump in this issue. I hope it will help you.　　In fact, when the submersible slurry pump is blocked during use, it will not only have a certain impact on the working efficiency of the equipment during operation, but also cause serious damage to the equipment itself, so it is also a reminder that we are using it too

　　The structure of the submersible slurry pump will be more intuitive. First, the equipment will use centrifugal force to drive the liquid from the impeller to the outer edge and obtain energy, and then leave the edge of the impeller at a higher speed　　What is the solution to this situation?Kirkuk,　　Then start the spray pump. It is specially used for control equipment such as fire fighting, sprinkler and water curtain in high-rise and low-rise industrial and civil buildings. It is also suitable for restaurants, stores, warehouses, underground garages and other places. The ordinary sprinkler head can be directly installed or hung on the sprinkler pipe network　　 Then tighten the compression nut on the packing gland evenly to make the liquid leak out in drops, and pay attention to the temperature rise outside the packing chamber.Blagoveshchensk , because there will be some difference between the marked head when using and the head when using. This is because the pipe itself　　Superior,KirkukISG single stage vertical pipeline pump, complete protection s, reasonable structure, convenient installation and high cost performance. In case of sudden power failure of the plant and emergency, the water pump will automatically start to supplement the pipe network pressure.　　It will burn out. If there is a heating problem in use, you can refer to the following reasons.

　　 Next, the water seal,KirkukVertical heavy-duty slurry pump, lock ring and other parts need to be installed.　　Consider the vertical separation level of the tail equipment.　　Moreover, explosive and toxic liquid will cause fire, explosion and poisoning and the consequences will be unimaginable.Marketing Department,　　The seal cannot bear the water pressure at this depth. Once the water leaks, the motor will not work normally, resulting in damage to the submersible slurry pump. The biggest difference between the submersible slurry pump and the horizontal slurry pump and the vertical slurry pump is that the motor of the submersible slurry pump and the shaft connected to the pump are integrated and sealed Closed.　　The high-pressure water flows to the space occupied by the original bubble at a very high speed, keep a small amount of cleaning water flowing along the shaft, regularly adjust the packing gland, check the packing and regularly replace the packing. The shaft seal water pressure and water volume shall meet the above (shaft seal inspection) requirements.

　　 install the front pump shaft first and then the rear bearing for the slurry pump of the filter press of the cylindrical bearing box.Quality assurance,　　When using the sand pump, be sure to pay attention to the steering divergence between the motor and the pump. The sand pump has an arrow on the pump to mark the main steering. After the power supply is connected, run the pump without load. Check whether the motor operates normally. During operation, be careful not to exceed the bearing on the pump support to avoid　　The waste water and dirt of conveying belt particles in factories, steel mills, power plants coal processing industries, drainage systems of urban sewage treatment plants municipal engineering, construction sites and other industries can also be used to pump clean water and corrosive media.　　After the submersible slurry pump adds a water gun to the support at the bottom of the submersible slurry pump, the hardened mud layer around the slurry pump will collapse rapidly under the applied water pressure, which will also increase the sand pumping area. This will also increase the sand pumping area,KirkukHH slurry pump, so there will be no buried pump when it is used. However,Kirkuk,　　Many users, including new practitioners of slurry pumps, often fail to distinguish the difference between submerged vertical slurry pumps and submerged slurry pumps. The names of submerged and submerged slurry pumps seem similar, but there are essential differences. What is the difference between submersible slurry pump and vertical slurry pump?　　The other mechanical seal is a split seal, which can be replaced without disassembling the slurry pump.　　Generally, the diving depth of the submersible slurry pump is not more than meters, and the operation is reliable. Why not more than meters? This is the crucial technical point of the submersible slurry pump, because the current sealing technology in China is more than meters, not because the slurry pump has a problem, but because

　　Potential energy, pumping water up high. However, once the pump can not absorb water, the equipment is shaped like a decoration, so what is the reason for this situation? How to solve it?　　I believe you have such a question when using the submersible sewage pump, that is, is this pump a submersible pump? Or is it a sewage pump? In fact, this question is very easy to distinguish. You can take a look at the following contents sorted out by Shanghai Shenquan.　　Rotate in the rolling direction until the friction between the impeller and the front guard plate stops, then use the adjusting bolt to move the rotor backward, record the forward and backward movement gap, evenly distribute it between the front and rear guard plates of the impeller until the gap between the impeller, the front guard plate and the rear guard plate is flat, stop, and tighten the two dust discs and fasten them on the shaft. adjustmentOK or not?,　　Generally, the diving depth of the submersible slurry pump is not more than meters, and the operation is reliable. Why not more than meters? This is the crucial technical point of the submersible slurry pump, because the current sealing technology in China is more than meters, not because the slurry pump has a problem, but because　　Stability and reliability of seals between pump bodies.　　 Inspection before installation: Check the specification size and quality of thick and thin accessories.

　　The use of water pumps is related to all aspects of our life. With the arrival of the May Day holiday, the water consumption will increase. Therefore, it is necessary for us to choose a suitable water pump.Inspection environment,　　 Assembly of rotor parts of submersible slurry pump Before assembly, apply a layer of lubricating oil on the mounting surface to protect the shaft hole from damage.　　The sand suction pump and sand water separator in the aeration grit chamber of the screw pump operation pre-processing unit are used to remove the sand particles in the sewage. It is necessary to ensure their normal operation so as to reduce the sand particles in the sludge and prolong the service life of the screw pump.　　It needs to be replaced in case of damage,SulaimaniaWQ submersible pump parameters,SulaimaniaQJ submersible pump, swelling and deformation, insufficient spring pressure, breakage, etc.Sulaimania,　When using the submersible slurry pump, the equipment may be burned out. The main reason for this phenomenon is improper operation. How should we prevent the burning out?　　Water flow into the bearing damages the bearing.　　 add water with manual pump. Some pump owners have their own hand pumps. They can also buy or manufacture their own small hand pumps. The gate valve shall be installed at the water inlet. After closing the valve inject a small amount of water into the water compressor to divert water. When the hand pump discharges water, it means that the pump is full
